  "textContent": "A microelectromechanical gyroscope includes a body (6) and a driving mass (7), which is movable with respect to the body (6) according to a driving axis (X) and is capacitively coupled to the body (6). The gyroscope moreover includes a driving device (3), which forms a microelectromechanical control loop (18) with the body (6) and the driving mass (7) and is configured for supplying to the driving mass (7) driving signals (V D1 , V D2 ) having a common-mode component (V CM ) and respective differential components so as to maintaining the driving mass (7) in oscillation according to the driving axis (X). The driving device (3) is provided with an actuation stage (23) configured for inverting in a controlled way the sign of the differential components of the driving signals (V D1 , V D2 ).",
